增强CT在判断肺癌手术切除可行性中的价值

Value of Contrast-enhanced CT in Judging the Feasibility of Excision of Lung Cancer

目的探讨增强多层螺旋CT(MSCT)在判断肺癌手术可切除性中的应用价值。方法回顾性分析2014年8月-2016年8月我院经手术或活检病理确诊的68例非小细胞肺癌(NSCLC)患者的增强MSCT影像资料,并与手术结果对照。结果增强MSCT评估肺门、纵膈大血管受侵犯及膈淋巴结转移与手术结果的一致性分别为86.76%、83.82%,一致性比较满意(Kappa=0.68、0.61),敏感度分别为77.78%、80.0%,特异度分别为90.0%、86.05%。增强MSCT评估NSCLC可切除性与手术结果的一致性为79.41%,一致性比较满意(Kappa=0.57),敏感度为85.37%,特异度为70.37%。结论增强MSCT可反映血管受侵犯、纵膈淋巴结转移情况,为胸外科医师判断NSCLC可切除性提供客观资料。

Objective To investigate the application value of contrast-enhanced multislice spiral CT （MSCT） in judging the feasibility of excision of hmg cancer. Methods The contrast-enhanced MSCT images of 68 patients with non-small cell lung cancer （NSCLC） diagnosed by operation or biopsy in our hospital from August 2014 to August 20J6 in were retrospectively analyzed and were compared with results of operation. Results The coincidence rates of contrast-enhanced MSCT in evaluating puhnonary hi]at and mediastinal great vessel invasion and mediastinal lymph node metastasis with the results of operation were 86.76% and 83.82%, the consistency was satisfying （Kappa=0.68, 0.61）, the sensitivities were 77.78% and 80% respectively, the specificities were 90% and 86.05% respectively. The coincidence rate of contrastenhanced MSCT in evaluating feasibility of excision of NSCLC with the results of operation was 79.41%, the consistency was satisfying （Kappa=0.57）, sensitivity was 85.37%, and specificity was 70.37%. Conclusion Contrast-enhanced MSCT can reflect the invasion of blood vessels and mediastinal lymph node metastasis, providing objective data for the doctors to judge the resectability of NSCLC.
